LumaWerx 3157CK Dual Color Switchback LED Bulb-60SMD





Product Description

Exclusive – T25 3157CK LumaWerx™ dual color SMD LED Bulbs with TruSwitch technology are a great way to improve the look of your vehicle by having a modern bright white color while in parking light mode are and a street legal amber color when the turn signals or flashers are activated. Please note, a 3157CK is not the same as a standard 3157, for standard 3157 bulbs, click here.


Upgrade – These are an inexpensive and subtle way to upgrade your vehicle’s indicator/running lights. No white on while amber flashes, beware of fakes! These bulbs truly flash only amber on turn signal/flasher mode and bright white during running/parking lights. Also offered in a standard 3157 LED Switchbackversion socket.


Technology – LumaWerx™ TruSwitch technology is built in to every bulb allowing one color to completely disengage and shut off while the other color is active, something many have tried to copy. TruSwitch technology allows for the white running light to completely shut off while the turn signals or hazards flash allowing for the signals to clearly and easily be seen by oncoming traffic.


Dual Color – The LumaWerx™ dual color LED bulbs are lit as a powerful white emitting light during the parking light mode and blink amber when the turn signals or emergency flasher lights are engaged. Once signal or flasher is turned off, the bulbs will go back to white. When installing LED bulbs into turn signals you may need a set of load resistors or flasher relayto prevent hyper or rapid flashing. See them in action.
